1 Claim (Cl. 185-37) This invention is a pumping apparatus or shafts 21 anchored at 22 upon each side of the mechanism whereby the energy stored in wound pump casing, and are placed in mesh with the springs may be utilized for driving or operating drive gears 6. Drive wheels 23 are rigidly mounta water pump or like device. ed upon the outer sides of the pinions and have 5 One object is to provide a practical and sublaterally aligned and eccentrically positioned co stantial form of such mechanism which may be crank pins 24 extended therefrom. A U-shaped compactly associated with the pump and having connecting link 25 has its free ends journaled at two spaced spring drums for positioning one at 26 upon the pins 24,, while the'bight of the link each side of the pump, with gear and lever 0011- is journaled at 27120 the upper end of the ver- 10 nections directly to the pump rod. tically reciprocating pump rod 28. The arrange- Another object is to provide a pumping appament is suchthat a line connecting the centers ratus including dual spring and gear assemblies of the pinions 20 will pass through the pump rod wherein energy may be stored by crank action and 28, whereby the pins 24 swing equally to either redelivered as desired for the operation of the side of the rod 28 in the operation of the device.
